This topic provides information for creating your own installation exit routines. For examples of SAMPLIB jobs pertaining to these installation exits, see SAMPLIB members.
Each of the installation exits (CBRUXENT, CBRUXEJC, CBRUXCUA, and CBRUXVNL) are linked to (on each invocation) using the MVS LINK macro and must reside in a library in the LNKLST concatenation. Because the exits are called (on each invocation) using the MVS LINK macro, a new copy of the exit can be LINKEDITED on the system at any point in time and OAM will pick up the new version. However, if the exit had been previously disabled or return code 16 had been used to bypass the exit, to re-enable the exit, you must also restart OAM or issue the LIBRARY RESET command.
